+Hash chained covenants in general all have about the same plateau of
+functionality, which seems roughly reasonable to add to Bitcoin as it is
+today but suffer from being limited and hence likely only a stepping stone
+to greater functionality and unless whatever's put in now cleanly extends
+to supporting more in the future it's likely to turn into a legacy
+appendage which has to be supported. So my generic suggestion for this sort
+of thing is that it should be proposed along with a plan for how it could
+be extended to support full-blown covenants in the future.
+
+Another probably unhelpful bit of feedback I have is that Bitcoin should
+probably be taking verkle trees seriously because those can have
+substantially lower size/cost/weight than merkle trees. That doesn't just
+apply to this proposal, but to Bitcoin in general, which doesn't seem to
+have any serious verkle tree proposals to date.
